A Microfluidic Device for Opto-Electrochemical Sensing

Luo T.-J.M., Choi Y., Huh U., North Carolina State University, US

To integrate functionality of transmembrane proteins to devices, a platform compatible with proteins and phospholipids membrane is required. In our effort to address the needs for current and future research, we report a microfluidic device [...]

DNA-DNA Interaction on Dendron-Functionalized Sol-Gel Silica Films Followed with Surface Plasmon Fluorescence Spectroscopy

Kwon S.H., Hong B.J., Park H.Y., Park J.W., Knoll W., Park H.Y., Park J.W., Center for Integrated Molecular System., KR

Since we observed that dendron-assembled surface providing a proper spacing between immobilized DNAs showed high single nucleotide polymorphism discrimination efficiency for DNA microarrays(1), the nanoscale-controlled surface is examined with surface plasmon field-enhanced fluorescence spectroscopy (or [...]

Rare Earth-Substituted BI 4Ti3O12 Nanocrystalline Thin Films: Synthesis and Ferroelectric Characterization

Tomar M.S., Katiyar R.S., Perales-Perez O., University of Puerto Rico, Mayaguez Campus, PR

In this work we present the synthesis of bare and rare earth (Ce,Er,Pr)-doped Bi4Ti3O12 (BIT) nanocystalline thin films using a method based on the Sol-Gel process. Thin films were deposited by spin coating on Pt [...]

Microstructure and Stability of Polymer Nanocomposite

Yin J., Wang X., Fan Y., Lin J., Lei Q., Harbin University of Science and Technology, CN

In this paper, the inorganic nanoparticles (SiO2, Al2O3) hybrid Polyimide (PI) films are prepared by Sol-Gel. The films are yellowish and transparent and the thicknesses are about 2050 m. The microstructure and nanoparticle distribution in [...]

Morphology effect dependent on the synthesis method of KxIr1-xO2 system

Ramírez E., Chavira E., Baños L., Soto Guzmán A.B., Guzmán J., Flores C., Universidad Nacional Autonoma de Mexico, MX

We focus our attention on the synthesis of the solid solution of KxIr1-xO2 with x = 0.25. This solid solution was obtained by the solid-state reaction and sol-gel method using IrO2 and K2CO3 as starting [...]

Preparation of Sb Doped SnO2 SPM Tips and their Use as Transparent Probes in STM Induced Light Hybrid Microscopy

Tätte T., Jacobsen V., Paalo M., Branscheid R., Kreiter M., Mäeorg U., Saal K., Lõhmus A., Kink I., Tartu University, EE

Development of various kinds of sharp needles has been in focus of investigators since their application as sensors in scanning probe microscopy. Although transparent and conductive tips lead to several fascinating applications like STM/SNOM hybrid [...]

Fabrication of Complex Diffractive Structures in an Organic-Inorganic Hybrid and Incorporation of Silver Nanoparticles

Scholes F.H., Smith F.L., Furman S.A., CSIRO Manufacturing and Infrastructure Technology, AU

Organic-inorganic hybrids have recently attracted considerable interest. These materials, which are synthesized by the highly versatile sol-gel process, consist of interpenetrating organic and inorganic networks at the nano- to molecular size scale. Incorporating photo-polymerizable groups [...]
